Consider the $JK$ Flip flop made using NAND gates given below
What is the characteristic equation of $JK$ Flip flop ? ( $Q$ represents the present state and $Q_{n}$ represents the next state of the flip flop)
- $Q_{n}=\overline{J} Q+K Q$
- $Q_{n}=J \overline{Q}+\overline{K} Q$
- $Q_{n}=J Q+\overline{K} Q$
- $Q_{n}=\overline{J} Q+K \overline{Q}$
